Abstract

The aim of the invention is to suppress interference signals in the receive branch of a modem (MO), which contains a transmit branch and the receive branch, of a household appliance (HG) equipped with a transmitting device for transmitting and a receiving device for receiving data signals. When using a receive circuit (EB) of the modem (MO) with an input circuit having a relatively high input impedance, a bandpass filter (BP) is connected in parallel to this input circuit. The resonance frequency of the bandpass filter is set to a value such that the frequency of the respective interference signal is either higher or lower than the relevant resonator frequency.
